  1. create a vlan interface
  2. assign a IP address to VLAN interface
  3. ping this IP address. BUT no any response.

Why I can’t ping this IP address?

If you are using a master port, vlan must be taken from the master port.

you are sure that the VLAN to mikrotik comes.?

  1. Turn off the vlan interface.
  2. With the other hand will generate traffic vlan
    3.c using torch tagget see if there is traffic on the interface

Thank you for your reply!

I use ether4-slave-local port, and connected to the trunk port on switch.
BUT this router can’t not decapsulate vlan tag, am I right?
How could I setting the interface like trunk port?
